It's an ok apartment. There is very little sunlight. The gym was closed for my entire visit. The dryer didn't dry my clothes at all, so I had to pack wet clothes when I left. The bathroom is a bit of a disaster. The sink spigot sprays out way passed the sink, so if you forget, you'll have to change your clothes because they will be soaked (it happened to me twice). The bathtub/shower should have a staircase installed to get in and out of.
On a positive note, the place is clean. Aside from how dark it is, it looks like the pictures. The location is pretty good, you're about a 10 minute walk from Soi 11.
I was very disappointed that I paid for an apartment with a gym, and it was closed the entire time, and the only accommodation the owner offered was to find a paid gym close by. I would not book here again or recommend it.
